Window Energy Efficiency

Low-e glass infographic showing heat flow and other factors of low-e glass.We only install windows with excellent U-factor values, low-emissivity glass, and the Green Seal of approval:

  • U-factor: This value measures the window’s insulation or the amount of heat it allows through. The lower the value, the better insulated and, thus, the more energy-efficient the window. Our windows have low U-values to ensure minimal energy loss.

  • Low-E glass: This standard is a newer measure in window technology that applies a microscopic, metallic coating to the window’s glass to reflect and direct heat energy into or out of your home. All our low-E glass windows are ENERGY STAR®-certified.

  • Green Seal approval: The Green Seal is an environmental certification that allows manufacturers, buyers, and homeowners to make informed decisions when purchasing windows. All our products meet these high standards.
